KEY MESSAGES

- Above normal temperatures are forecast through the upcoming weekend with a brief cool down possible early next week.

- There are low chances of rain Monday and Monday night.

SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 212 PM CDT Wed Oct 21 2026

High pressure continues to sit to the east of the area and continue to bring quiet and warm weather. Lowered low temperatures by 1 to 2 degrees from the NBM given clear skies, low humidity and light winds as well as trends the last several days. Low temperatures on Thursday morning will be in the mid to upper 40s. A few passing high clouds are possible Thursday morning. High temperatures Thursday were bumped to 74 to 77 degrees from east to west.

LONG TERM /FRIDAY THROUGH TUESDAY/

Issued at 212 PM CDT Wed Oct 21 2026

There is amplified ridging across the central Plains late this week into the weekend as a western US trough slowly shifts eastward. As the surface high pushes to the east Thursday night into Friday the pressure gradient across the region begins to tighten resulting in potentially breezy conditions Friday and Saturday. Clouds cover will also be on the increase Friday night into Saturday with warm but cloudy conditions. High temperatures both days will be in the 70s with Friday the warmer of the two days.

By Sunday, the ridge axis will shift eastward allowing southwesterly flow aloft to develop with a shortwave trough lifting northeastward and across the area on Monday. This storm system will also bring a cool front across the area. There is a lot of model variability on the timing of this front as well as the temperatures. There is a much as a 15 degree variation in models based on the timing of the front. High temperatures may linger into the 70s on Monday. There are low (15 to 30%) chance of rain. Rainfall amounts are expected to be light with less than a tenth of an inch expected. By Tuesday, high temperatures drop to the upper 50s to lower 60s.

AVIATION /18Z TAFS THROUGH 18Z THURSDAY/

Issued at 1159 AM CDT Wed Oct 21 2026

VFR CIGs expected for the next 24 hours at the terminals. Light southerly winds will become light and variable overnight. With the light winds overnight, there is some potential for fog development late overnight and into the early morning hours, especially across the immediate Mississippi River Valley. Confidence was too low to include with this package (less than 30%) but this will be something to monitor for future updates.
